Sol-gel synthesis of hematite nanoparticles and photo degradation of cibacron red FN-R dye

الملخص EN

This paper describes the synthesis of α- Fe2O3 nanoparticles by sol-gel route using carboxylic acid(2-hydroxy benzoic acid) as gelatin media and its photo activity for degradation of cibacron red dye .

Hematite samples are synthesized at different temperatures: 400, 500, 600, 700, 800 and 900 ᴼC at 700 ᴼC the α-Fe2O3 nanoparticles are formed with particle size 71.93 nm.

The nanoparticles are characterized by XRD , SEM, AFM and FTIR .

The 0.046 g /l of the catalyst sample shows high photo activity at 3x10-5M dye concentration in acidic medium at pH 3.-
